Question

In the following electrical network, the value of 'I' is

Options

• 2.3 A

• 3.4 A

• 1.8 A

• 2.8 A

Answer 1

3.4 A

Explanation:

I₁ = 2 + 1 + 3 = 6 A

I₂ = I₁ - 1.2 = 6 - 1.2 = 4.8 A

I₃ = I₂ + 0.8 = 4.8 + 0.8 = 5.6 A

I₄ = I₃ - 0.5 = 5.6 - 0.5 = 5.1 A

I₅ = I₄ - 1.7 = 5.1 - 1.7 = 3.4 A
